Comment 21 for bug 1368402

Thanks Thaddaeus for pointing me to this bug, i should have put more energy in searching for bugs in here - sorry.

By studying the provided information in this bug report and the referenced links and sublinks, i found a "simple" workaround that works for me (for now):

1. Get sure natural scrolling is setup in Gnome (was already the case here).
2. Setup normal (non-natural) scrolling in XFCE
3. Run '/usr/lib/gnome-settings-daemon/gnome-settings-daemon' after each XFCE session start. It just needs to start up and can be killed right afterwards, either way it complains about another settings daemon running!

Another way could be fiddling around with xinput (i assume gnome-settings-daemon is doing exactly that in the background), but i was too lazy to adapt that to my case...
